9 Claims.

In machines of the type controlled by perforated record cards which are utilized for accounting, bookkeeping and statistical purposes, it is essential in many cases that the printed records obtained under control of the perforated record cards contain not only numerical data but in addition thereto address data. One manner in which this may be obtained consists in representing the addresses by perforations in the perforated record cards so that the perforations representing the address cause, upon the passage of the record card through an alphabet printing tabulating machine, the printing of the address in addition to the numerical data which is printed by the numerical printing mechanism of the machine under control of the fields of the record cards representingnumerical data. In some types of machines the record cards representing the addresses may contain only address representing perforations.

Another arrangement whereby address data may be printed has been disclosed in U. S. Patent No. 2,002,437. According to the disclosure in this patent, representations of numerical designations are punched on a record sheet in addition to the numerical data printed thereon. .The perforations representing'the designations, which are made in successive sections of the sheet, are compared with designations placed upon address printing plates which are passed through the same machine. Upon the agreement of the perforations on the sheet with the designations on the address printing plate, a printing operation is effected from the printing plate and the address data is thereby printed upon the section of the record sheet containing the designation perforations corresponding to the designations of the address printing plate from which the printing operation is effected. The operation of the combined, tabulating, punching and addressing machine is entirely automatic so that the successive sections of the sheet are imprinted with the related addresses. The address printing plates which are not selected for printing operations pass inefiectively through the machine.

The last mentioned method of operation is carried out by a special construction of an accounting machine such as, for instance, a printing tabulating machine which is provided with an address printing mechanism. The numerical data is printed upon the sheet under control of record cards so as to print the data represented by such record cards. The machine just described must be provided with a punching mechanism which causes under control of certain fields in the type of combined tabulating, addressing merical data is printed on the record sheet by of the record cards the Perforation of the sheet to represent the designation numbers related to the address printing plates from which printing operations areto be effected. The record sheet which is thus perforated may be then utilized to control the printing of addresses on the sheet machine heretofore described.

It is obvious from the above that the placing of the perforations in the record sheet must be effected by means of a punching mechanism incorporated in the tabulating machine. The method just described may be used in connection with other types of accounting machines such as adding machines, cash registers and the like which are, as a usual rule, not provided with any grlileaitis capable of printing addresses on a record ee In certain types of machines it is not or at least undesirable, to incorporate 23 3351 machines the special printing mechanism for punching address plate selection designations on the record sheet and this may be due, for example to the fact that space limitations in the machine will prevent the incorporation of such mechamsms or for the reason that the machines are already in commercial operation.

It is obvious from the preceding that in order to attain the object it will be necessary to provide a punching mechanism in order to punch the address printing plate selecting designations on the record sheet. The result, however, may be obtained by a method which primarily involves three steps and avoids the prior objections mentioned. In the first step of operation the numeansof' the usual numerical printing mechanlsm and at the same time a guide hole.is punched for each printed section of the record sheet. Such punching means for punching a guide hole may be easily incorporated in existing machines. In the second step of operation, by means of a separate punching machine the address printing plate selecting designations are punched on the record sheet under manual control. The perforations are made in the sheet in accordance with the address plate selecting designations printed upon the record sheet. In the third and final step of operation, the record sheet is passed through an address printing machine of the type previously described so as to print in each section of the sheet address data related thereto.

It is the principal object of the present invention to provide a machine by means of which the s PATENT O,FFICIQ.\

second step of the method may be carried out. In the preferred construction of the machine the sheet is fed through the punching machine section by section. The address printing plate selecting perforations to be made upon a section of the sheet are determined by the printed data on the sheet which is visually read by the operator.

By means of a key controlled punching mechanism punches are selected under control of the keys land operated by power means so as to efiect the punching operation. After the successive depression of the keys have selected the punches, the power means is released under control of a punch control release bar so as to cause the power operation of the selected punches. After the punching operation the record sheet is fed to the extent of one section and such feeding operation is effected automatically and during this operation the punch control release bar is locked against further depression. However, in order to speed up the operation of the machine, the punch selecting keys may be preliminarily operated in accordance with the numerical data on the successive section. By means of the guide holes previously described the sheet feeding mechanism will be automatically stopped when a guide hole is sensed by a sensing device in the machine.

lease bar.

The preferred electro-mechanical construction of the machine utilizes a one revolution clutch which controls the connection of the means for effecting the operation of the punches and the power drive and the engagement of such clutch is placed under control of the punch control re- When one revolution of the clutch is terminated an electrical contact is closed so as to cause energization of the sheet feeding clutch control magnet which thereupon causes the rotation of feed rollers so as to feed the record sheet to the extent of a successive section. The electrical circuit for the clutch magnet includes a stick circuit and such stick circuit is interrupted under control of a relay. The last mentioned re-' lay is controlled as to its effectiveness by the sensing device for the guide hole so that upon encountering a guide hole in the sheet, the relay is effective to'open the stick circuit of the clutch feed magnet and thereupon sheet feeding operations terminate. The relay also has provisions to cause the punch control release bar to be locked against depression during the time that the record sheet is being fed.

The sensing device for the guide hole is preferably adjustable so that the .area receiving the perforations may be selected limits.

Further objects of the instant invention reside in any novel feature of construction or operation within certain or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawings whether within or without the scope of the appended claims and irrespective of other specific statements as tothe scope of the invention contained herein.

A preferred embodiment of the invention is shown in the accompanying drawings, in which:

Fig. 1 shows a portion of the printed record sheet the two lower sections being shown periorated in accordance with the present invention and by the machine to be hereinafter disclosed, and shows in upper sections the form the sheet is in when such sections are to be perforated. The numerical data which is printed at the left-hand columns has, of course, been printed by the tabulating machine. These printed items represent group numbers at the extreme left, and in the next two columns groups of related items. The group numbers are represented in the sheet shown in Fig. 1 by the numerals 6420, 6425, 6431 and 6432. Each group of items comprises a number of printed items arranged one below another and below the lowermost item of a group there is represented a related total as well as an asterisk. In the present illustration only two groups of items are represented indicating, for example, weights and amounts. In some instances more columns of items are printed upon the record sheet. It is pointed out that since the second group from the top comprises a single item, this item also represents the group total.

On the record sheet shown in Fig. 1, and which is to be passed through the punching machine, there is also provided a single guide hole I20 for each group of items and such guide holes are, as heretofore pointed out, effected by means of a specially provided punch incorporated in-the tabulating machine which produces the printed record sheet. The guide holes, as has been explained, serve in the present machine to control the extent of paper feed and terminate such record feeding operations so as to position the sheet beneath the punches in such a position that the lowermost hole positions of the coded perforations is on the same horizontal line as the guide hole.

To more clearly illustrate, it will be noted that for a group of items the group number, 6431, is printed on the record'sheet shown and by means of the present punching machine the correlated section of the sheet is perforated so as to represent by the code of perforations illustrated in Fig. 10 the digits, 6431.. The positioning of the sheet so as to receive these perforations is placed under control of the guide hole I20 related to the groups of items. v I

In the presentinstan'ca'a guide hole I20 is correlated with each group of items. Obviously, if the printed record sheet comprises successively printed items which are not correlated, a guide hole I may be provided for each line of printed items, or one for each total if only totals are printed on the record sheet. In Fig. 1 it has been assumed that the guide hole |2|| shown is correlated with the second item of each group but obviously the guide hole could just as well be coordinated to the first or any other item or the total of each group.

In Fig. 1 it has been assumed that the record sheet has been fed through the punching machine constructed according to the-present invention so that the two lowermost sections thereof are punched to represent by the code of perforations the numbers, 6431 and 6432. The guide holes I20 for such sections serve to determine the position of the sheet for receiving such perforations. Since in the addressing operations a supplemental guide hole is desirable the present machine is preferably provided with a supplemental punching means to cause the punching of a supplemental guide hole and such perforation is effected simultaneously with the address plate selecting designation perforations and such perforations I25 are preferably located adjacent the holes I23 and for each section are preferably located in a horizontal line.

Since the construction of the special punching means in the tabulating machine for perforating the guide hole I20 in the record sheet requires that such perforations be placed at a definite and unchangeable position in the sheet and since, on the other hand, the address printing may be required on the sheet at various positions, the supplemental guide hole I25 may be displaced with respect to the guide hole |20. For this reason, the sensing device for the guide hole i2!) is preferably adjustable so that the location of the special guide hole I25 may be selected in accordance with different requirements.

General construction of the machine The machine includes a set of punches which are selected for perforating operations by means of combinational punch selector bars'and the adjustment of these bars is determined by the depressed keys of the keyboard. The operation Framework construction of the machine and parts carried thereby The framework of the machine consists of two side frame plates N (Fig. 2) which are transversely connected by means of rods l2 (Fig. 4) and also by angle plates l3 and I5 also shown in Fig. 4. The angle plates l3 and I5 are connected with each other by means of a plate 2| (see Fig. 2). An angle plate l4 (Figs. 2 and 4) has one end thereof secured to the right end side frame plate II and at the other end to the plate 2|.

Secured to the rearward extremities of the side plates is a pair of brackets l1 and (as best shown in Fig. 2), these brackets form the sup- 31 (Fig. 4) which is supported by the angle bars 'is fastened to a gear 46 (see Fig. 2). The gear 46 X y 3 porting means for the record sheet supply roll, which is to beperforated by the machine. The record sheet is fed from the supplyroll through the machine and after it has been perforated the perforated portion is wound upon a storage roller 5 IS. The storage roller is carried by forwardly extending brackets N (Fig. 2) also carried by the side frame plates I, l The shafts 25 (Figs. 3 and 4) for the two pairs\ of feed rollers 23 are journaled inthe side frame plates H and it will be seen from Fig. 4 that the feeding rollers are positioned at both sides of the punching mechanism. The storage roller l9 has a frictional drive connection to the motor and which driving connection will be subsequently described. A motor (Figs. 3 and 4) comprises the prime mover for the machine andis suitably supported by the framework of the machine and is located between the side frame plates H at the bottom of the machine. From the motor 30 there is a drive for operating the punching mechanism and also a driving means for rotating the feeding rollers 23 and which driving means will be subsequently described.

Secured to the angle plates l4 and I5 are .upstanding brackets 3| and 32 (Figs. 3 and 4), the upper ends of which are transversely connected by a bar and secured to said bar there is a bracket 33.' To the angle plate I3 there is secured a bracket 34 at the front part 01 the machine and the brackets 33 and 34 together form the supporting means for the keyboard 35.

The punches 98 are supported by a carrier bar l4 and I5. A die plate 38 (Fig. 4) is located beneath the punches and has an opening to a box 39 which receives the chips formed by the punching operation. The punch selecting mechanism for selecting the punches is mounted beneath thekeyboard 35. Between the brackets 3| and 32 the guiding means and the driving means for the punch selectors are arranged.

Driving mechanism Secured to the armature shaft of the motor 30 is a worm gear 4| (Fig. 3) in a driving engagement with a worm gear 42. The worm gears 4| .and 42 have the same number of teeth and obviously a gear ratio of 1:1. The worm gear 42 is an integral part of a sleeve 43, which, in turn, is loosely mounted upon a drive shaft 44. Integral with the sleeve 43 is a worm wheel which is in driving engagement with a worm gear 45 which a is adapted through a train of gears 41, 48, and

49 to rotate a clutch wheel 50, the clutch wheel 5|) and gear 49 being connected together by means of a sleeve which is loosely mounted upon a drive shaft 5|.

The clutch wheel 5|! is one element of a onerevolution clutch adapted to effect a driving engagement between the motor and the operating means for the aforementioned punches. The clutch also includes an arm 56 which is secured to. the drive shaft 5| (Figs. 2, 3, 4). The shaft 5| is journaled in the brackets 3| and 32. Pivotally mounted upon the clutch arm 56 is a spring urged clutch pawl 52 and said pawl is in the plane of the clutch wheel 50, and is normally held out of operative engagement therewith by means of a clutch release arm 53. The clutch release arm as well as a rebound preventing arm 51 are pivotally mounted on the bracket 32. when the clutch release arm 53 is rocked by theforward shifting 6:1 .1. bar 54, (Fig. 3 piv'otally "connectedthereto, the .clutchpawl 52 is released 7 l for gage e twah the clutch wheel 50 thereby effecting a driving connection between the arm 4 5 6 and the shaft 5| so that the drive shaft 5| will be rotated for the extent" of one-revolution. When one-revolution of the shaft has been ef- T .fected, the clutch release arm having been released, ,will now bein the path of the clutch pawl 52, and effect its disengagement from the clutch wheel 5|]. "The' constructionfand operation of 'the one-revolution'clutch just described are very well known in the art to which the present invention appertains; and for this reason is only briefly described and explained herein. I

As previously" indicated the pairs of feeding rollers23 are driven by the motor through a frictional driving means which-will now be described. From Fig. 3 it will be seen that the sleeve 43 terminates at its left and in a bevel portion which is one element of the friction clutch." This' element is received by a similar shaped recess of the supplemental frictional drive element 55 which isslidablymounted on the shaft 44 andhas a sliding key connection therewith. In-order to effect the frictional driving connection between the elements of the friction clutch there is provided a clutch control magnet 50, the armature of which is pivoted at 6| andwhich has depending extensions carrying pins engaging a groove of the clutch element 55. It is obvious that when themagnet 60 is energize-d the clutch member 55 will be brought '60. l ati'on'a subsequent slippage will be effected be-- into frictional engagement with the correlated friction element of'thecontinually driven sleeve 43 so as to effect arotation of the sleeve 43.

From Fig. 3 it will be seen that the shaft 44 is provided with threaded portions formed as worm wheels meshing with worm gears secured to the shafts 25 to which are fixed the feeding rollers By means ofthe frictional drive connection just described the shaft 44 is also adapted to rotate the paper feeding storage roller i9. To this end the shaft 44, as best shown in Fig. 3, is adapted to rotate a circular member H! which is preferably a rubber roller 63.- The latter is ment 64 which is preferably also a rubber roller and. which is secured to the supporting shaft of the paper sheet storage roller i9. Due to the ratio of the diameters of the members 63 and 64 the paperst'orageflroller I8 is rotated so as to be capable of winding up the paper strip to a greater extent than that fed by the rotationof the feeding, rollers .23 so that, independently of the diameter of the paper feeding storage roller, the

latter will always tightly wind upth e paper strip and when a suflicient rotation has been given to the paper storageroller l9 to effect this opertween the elements 63 and '64. In order to enable the. manual feeding of the record fsheet through the machine the shaft 44 is provided .atits extremity, as best shown in Fig. 3, with a knobor handfwheel 65.

I order to guide the record sheet through the I ,ma'chine, guide plates I (Fig. 4) are provided.

Since they groupnumberto be punched upon the record sheet ,must be visually read from the record sheet, one of the paper guide plates I35 I is provided ifwith a cut-out portion j forming a window |3 ,6, bestjsho wn in Fig. 2. Across this. "window there is extended a guide wire I31 which indicates the number next to be punched.

' The arrangement is such that the punches '98 will effect the punching" in an area which is in juxtaposition to the printed group numbers'and the guide hole I25 will be punched on the same horizontal line asthe guide hole I20. From "Fig. 2' it will'be obvious that the record sheet has been fed to'such an extent thatthe group number,; 6425, is visible through the window I36 and is just above the designating element lil'lv and the last-mentioned number is now to be punched by a punching mechanism now to be described in'detail.

Keyboard and control keys The present machine discloses a keyboard comprising four rows of keys 88 designated 8'0, and'thusthe machine has a capacity for punching in four-denominational places. This capacity is usually suificient for ordinary requirements but the capacity of the machine may be altered to meet different requirements by varying the size of the keyboard and associated punching mechanism. In Fig. 2 only the lower keys of the four .rowsare shown so as to more clearly illustrate certain other parts in this figure. In addition to the four rows of numeral keys 30 the machine is provided with a vstart key I1 (Figs. 2 and 3) which, upon depression thereof,

closes start key contacts 12. In order to initiate a punching operation, after the punches have been selected by the depression of the keys 80,

' a manually operated punch control release bar 13 is provided and as best shown in Figs. 3, 7 and 8 the punch release bar 13 is carried by a pair of bell crank arms 13a one of which is secured to a shaft 14. To the shaft 14. thereis secured a depending arm 19 which'is pivotally connected to the bar. 54. It is obvious that when the punch release bar 13 is manually rocked the shaft 14 and arm 19 will also be rocked to shift the bar 54 to the left, as shown in Fig. 3, thereby effecting the clutch engagement in the manner previously described.

Below the release bar I3, there is provided a relay H (Figs. '7, 8.) the armature TB of which is underneath one of the bell crank arms 13a when the magnet of the relay I1 is deenergized.

However, when the. magnet of relay 11 is enerv xgized the armature 16 will be drawn to the right, as viewed in Fig; '7, so as to unlock the punch release bar 13 permitting a punching operation.

Figs. 3 and 4 disclose only several of the numeral keys and the lowermost key of-a row is shown in depressed position. Each numeral key 80 is connected by a Bowden wire with a punch bar selector stop 8| (Fig. 4) there being a row of these stops, one for each key 80 and actuated thereby. The selector stops 8| are normally in elevated position out of the path,

of stops 82 of the related punch selection bar 83. The lower ends of the Bowden wires are slidably'mounted in a frame plate I30 and the selector stops 8| are slidably mounted in spaced frame plates. I40 and I50. The frame plates 130,

- I40 and |50comprise a frame which is supported by means of rodssecured to' aplate I60- which, in turn, is fastened to one of the side frame plates fl and the plate 2|.

Slidably mounted on the frame plate I40 is a series 'of detentplates 68 there being one provided for each row ofselector stops 8| and the detent plates are of a construction which is very well known. Each detent plate is] adapted to hold the actuated selector stop 8| in depressed position until the completion of the punching operation. At the completion of the punching operation a cam 84 fixed to the shaft will, in

. guided in a casing and together with the casing they are depressed by means of a punch operating cam. The casing is shown in section in Fig. 4 and in end view in Fig. 5 and comprises a U- shaped frame I3I. Referring to Fig. 5, to the U-shaped frame I3I there are secured brackets I4I carrying sleeves I5I which are slidable upon guide rods 89 fastened to the angle plates I4 and I5. Between the brackets MI and the angle plates are located springs 90 which normally urge the frame upwardly so that the upper plate of the U-shaped frame I3I is in direct engagement with a punching cam 96, as best shown in Fig. 4.

The punch selector bars 83 are supported and slidably guided by means of combs I32 and I33 (Figs. 4 and 5) which are carrierd by the U- shaped frame I3I and also by means of guide rollers I23 which are loosely mounted upon rods I22 carried by the U-shaped frame I3I. The selector bars 83 are provided with punch selecting elements 9I (Fig. 4) adapted to overlie one or more of the punches 92 and the punch selecting elements 9| are so arranged that upon the adjustment of a selector bar 83 to any of the ten different positions punches 92 will be selected which will punch the sheet with perforations representing the digits by the combinational designation shown in the code in Fig. 10.

Each selector bar, as best shown in Fig. 4, is connected at its right end to one extremity of a wire I2Ia and the other extremity of the wire I2Ia is connected to a reduction roller 93 at the periphery thereof of its larger diameter. The reduction roller 93 also has aportion of a smaller diameter to which is connected one end of a wire I2 Ib and which wire is joined to a-rod 99 through a spring 94. The rod 99 is carried by a pair of arms 95 which are pivotally mounted in the brackets 3I and 32 and one of said arms 95 has a forward extension adapted to be actuated by means of a cam 91 secured to the shaft 5|. The timing of the cams 96 and 91 is such that upon the release of the one revolution clutch the cam 91 will first rock the arms 95 and the rod 99 thereby extending the springs 94 which cause the rotation of the reduction rollers 93 and through the wires I2Ia draw the punch selector bars 83 to the right until the stops 82 of the selector bars engage the selector stops 8I which have been actuated by the previous depression of the keys- 80. In the normal position shown in Fig. 4, the initial tension .of the spring 98 connected to a related punch selector bar 83 is greater than the initial tension of the spring 94 but upon the extension of the spring 94, in the manner just explained, the tension of spring 98 will be overcome so that the punch selector bar 83 will be moved tothe right until stopped by one, of the punch selector stops and held in such position thereby selecting certain of the punches 92 for operation. v

when the punches have been selected in this 5 manner the cam 96 will thenfbe. effective to depress the punch operating frame so that the selected punches 92 will be force through the record sheet and into the die 38. Upon further rotation of the punch operating cam 96 the: 0

punch operating frame will return to its\normal position and the cam 96 will thereafter relax the tension of the springs 94 so that the punch selector bars 83 may return to home position by means of the springs 98. However, before the 10 return of selectors 83 the cam 84 will rock the arm 85 shiftingall of the detent plates 68 to the left to release the selector stops 8|. The record sheet is still being fed to the next section and, therefore, it will be possible to depress the keys to select punches to' represent the group number of the next section. viously depressed keys will be an indication to the operator that the keys can again be depressed.

Perforating means for punching guide holes In order to effect the punching of the supplemental guide hole I25, which has a function previously explained in connection with the description of the record sheet shown in Fig. 1, a supplemental punch I25 (shown only in Fig. 2) is provided. The supplemental punch is carried by the punch operating frame and is therefore effective to perforate the record sheet with a guide hole I25 each time that the sheet is perforated by the selected punches 92.

The guide hole I20 is sensed in the present machine by an electrical sensing device comprising brushes IOI (see Figs. 5 and 6) which are carried by an adjustable carrier I02 which is of insulating material and is slidably mounted in the die plate 38. The sensing. brushes IOI pass through the guide holes I 20 and make contact with a contact plate I04. By means of a pinion I03 the carrier I02, and thereforethe brushes IOI, may be adjusted in the direction of the travel of the record sheet. As will be subsequently explained the feeding of the record sheet continues so long as the brushes IOI are prevented from contacting the plate I04 through the record sheet and when the brushes IOI make contact therewith through a guide hole I20 record sheet feeding operations are terminated. Obviously, by the adjustment of the brushes IN the extent of paper feed may be varied and therefore the area in which the numeral representing perforations and the guide hole I25 are to be located may be selected at will, for reasons previously explained.

General summary of operation To start the operation of the machine the printed record sheet (Fig. 1) which is to be punched is inserted in the machine and the leading portion thereof which is unprinted and unpunched is manually inserted and fed through the machine and wound upon the storage roller I9. As previously stated the manual record sheet feeding operation may be effected by means of the knob 65 (Figs. 2 and 3). -Thereafter the main line switch II3 (Fig. 9) is closed so that the motor 30 receives current by means of the The release of the prewire H9 to the other line side H2. It will be obvious, therefore, that even if the start key II is released the sheet feeding operation will continue until the first guide hole 920 encounters the sensing brushes Ilil. This will cause, as

- shown in Fig. 9,"the energization of a relay magnet 'II and the latter will attract its armature I6 and open contacts I43 (Figs. 7 and 9) thereby opening the stick circuit for the card feed clutch magnet 60 and terminate sheet feeding operations. The energization of-the relay magnet 11 will, as shown in Figs. '7 and 9, attract its armature I6 so as to unlock the punch release bar I3.

Thereafter'the punch selecting keys 80 are depressed in accordance with the group number visible'through the window I36 (Fig. 2) and printed on the section of the record sheet which is to be punched. The depression of the keys 80 will actuate certain of the punch bar selector stops BI (Fig. 4) and when all of the keys 80 have been depressed the punch release bar .13 is now depressed to cause the engagement .of the one'revolution clutch fill-52 shown in Fig. 3 to thereby cause the rotation of the shaft 5|. accordance with the actuated punch bar selector stops 8| the selector bars 83 will be differentially positioned so as to select cetain of the punches 92. Thereafter the punch operating cam 96will cause the depression of the punch operating frame so that the'selected punches 92 will perforate the record sheet to represent by combinational designations the printed group num- I her. In addition to this punching the supple-1 mental punch I25 (Fig. 2) will punch the record sheet with a second guide hole I25.

Shortly before the completion of ,the punching operation a cam II 5 secured to the shaft 5% (Figs.

4 and 9) will close contacts II4 to cause the reenergization of the magnet 60 thereby automatically initiating the feeding of the record sheet.

When such feeding operation is initiated the guide hole I20 will'be .moved away. from the brushes IllI thereby deenergizing the relay 'II so as to cause the closure of the contacts I43 and permitting the closure of the stick circuit .for

the card feeding clutch magnet 60 through such contacts I43 and the contacts I42: As will be obvious such stick circuit will remain established after camrcontrolled contacts II 4 are opened.

Shortly after the punching operation is initiated the detent plates 68 (Fig. 4) will be moved to theleft to release the depressed keys 80 and while .the record sheet is being fed to position the next section to the punching position the'numeral keys may be depressed in accordance with the. group number of the next sectionif such is visible inthe machine or is noted before the record sheet. feeding operation is started. The. punching operation is, however, prevented from occurring while the record sheet is being fed due to the fact that relay magnet 11 is deenerg'ized during the record feeding operation so that its armature will lock the punch release bar I3.

When the guide hole I20 of the second record keys 80 have already been depressed in' accord? clutch magnet 6,0. Record sheet feedlng-opera-' tions will-now' be terminated and if the numeral ance with the group'nu 'mber of the second'sec-'-' tion of the record sheet the punch'con'trol' release bar I3 may then be depressed. Punching place' and re -starting of the record feed .will take in the manner previously described.

When the last. section of the record sheet has been punched the trailing end of the record sheet may be manually fed out of the machine by the rotation of the knob 65 (Fig. 2). 7
